CONCRETE REINFORCEMENT.

Specification of Letters Patent.

Patented Aug. 30, 1910.

Application filed March 24, 1909. Serial No. 485,361.

To all whom t't'mwy concern:

-Be it known that I, citizenof the United StatesQand a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Concrete Reinforcement; and I do herebydeclare the following to be 'a full, clear, and exact description of'the' invention. such as will enable others skilled in the art to which it appertains to make and use the-same, reference being bad accompanying drawings, and to. the figures of reference marked thereon, "which form a part of this specification.

My invention relates to the construction of floors or the like of reinforced concrete; and it has for its object the provision of simple and, improved means for reinforcing the floors or- 'other slab structures at the heads of supporting columns, materially strengthen the floor or other slab at such points-in an economical and eificient manner.

The constructionand arrangement of the parts of the inventionare fully describedin the'following specification, "and illustrated inthe accompanying drawings, in which,

Figure 1 is a plan view of the reinforcing structure, and Fig; 21s a side elevation of a floor and supporting columns with a portion of the concrete broken away to disclose the reinforcing structure.

Referring to the drawings, 1 designates a sup orting column having its upper end pre erably formed -with an enlargement or cap 2, and 3 the 'floo'r or other superstructure supportedby the column. The columns are plurality of longitudinallydisposed-rods 4', which are arranged around a common point and have their upper ends projected to near the surface of the floor 3 or the like if there is no columnplaced above the slabs, and if so the rods may be continued'into the same.

The upper ends of these rods are held in position by the vertically .s aced encircling rings or hoops 5, 5, as

own. [The reinforcing structure over the column heads comprises a plurality of rods 7', one of which is bent around intermediate the rings or hoops 5, 5 with its each column rod 4 from such rings in diverging to the whereby to ,of vertical column rods, a 1160 -diating therefrom,

fromm divergmg of said rods, a' plurality of V-sha'pe with the looped end .of each hooked around a column rod intermediate said hoops or V -form, as shown. Resting on the legs GEORGE V. RHrnns, a

of the rods 7 preferably in substantially concentric relation to each other and to the column axis are two or more rings 8 of different diameters, thus combining with the rods 7 to form a net-work over the columns.

.The rods 9 are the reinforcing rods of the floor slabs. These rods run in groups from one thick section of floor or column head to another on both rectilinear and diagonal axes and preferably cross the column cap reinforce'ment over the rings 8 and between or on top of the hoops- 5. Only two of such rods are shown in the drawings;

It is thus apparent that by arranging the reinforcing rods in over the column heads.

I wls'hitunderst o d'that my invention is not limited- ,to anyzspecific construction or the manner shown 'a very strong and rigid structure'is provided arrangementof the parts, except inso far as such limitations ares ecified 1n the claims.

Having thus by Letters Patent, is,-

- .1. A reinforcing structure for column slabs, comprising, in combination, a plurality Y embracing suchrods near their upper' en s, -'r-ods bentaround the column rods above such hoop in descri ed my invention, what I claim as new and desire to secure a common 'plane'and having their legs ra- I and a ring-like member resting-on the legs of said bent rods. 2. A reinforclng structure for column slabs, comprisin in. combination, a plurality-of vertica column rods, a-hoop embracing said rods-near their upper ends, rods bent around the columnrods above said hoop and having their legs radiating therei form, such legs being substantially equidistantly 'spaced,. and a plurality of rings of different diameter disposed a'roundthe column rods and resting upon said legs. I

3 A reinforcing stliucture for column supported ,floors or the like, comprising in combination, a pair of hoops encircling the-upper ends [rods bentinto in a common plane and having their legs a set of vertical column rods,

ioo

radiating outwardly, a plurality of rings of clifl'erent diameter encircling the column rods and supported by the V-shaped rods,

and a plurality of floor rods crossing such 5 column head reinforcement and supported thereby.

In testimony whereof, I have hereunto j GEORGE v. RHINES. Witnesses C. W. OWEN, D. C. WALTER.
